3D Viewer is a streamlined and fast graphic editing application that allows users of all knowledge levels to quickly load files of common 3D filetypes and view 3D model meshes, textures, materials and animations data inside high-quality staging environment. This app is especially useful to users who want to take a closer look at various 3D model files when they are on the go or are away from their work PCs. Instead of installing a wide variety of large (and expensive) 3D editing applications to every PC they want to get some work done, they can instead install this small viewing app and proceed to view and inspect 3D models at their own pace. The app supports all the commonly used 3D model filetypes, including BX, STL, OBJ, GLB, GLTF, PLY, and 3MF.

Developed directly by Microsoft Corporation, this 3D viewing app is fully compatible with Windows 10 and offers a surprising number of features inside of its lightweight package. This includes extensive support for model staging, setting up custom lightning, background environment properties, extensive camera controls, integration with Paint 3D and Print 3D applications for customization and 3D printing of loaded models, animation browser and playback tools, support for browsing and purchasing of community-made models via 3D library showcase section, and even built-in support for observing loaded models in Mixed Reality – Microsoft’s own standard for handling AR/VR content for multimedia and professional uses.

While this 100MB+ app does not allow users to modify any of the core 3D model data, it represents a great tool for inspecting the 3D model down to their smallest details.

3D Viewer is 100% free for every Windows 10 user and can be used without any restrictions on both your home and work PCs.
